SAF1760  
Hi-Speed Universal Serial Bus host controller for embedded  
applications  
Rev. 2 — 19 June 2012  
Product data sheet  
1. General description  
The SAF1760 is a Hi-Speed Universal Serial Bus (USB) host controller with a generic  
processor interface. It integrates one Enhanced Host Controller Interface (EHCI), one  
Transaction Translator (TT) and three transceivers. The host controller portion of the  
SAF1760 and the three transceivers comply to Ref. 1 “Universal Serial Bus Specification  
Rev. 2.0”. The EHCI portion of the SAF1760 is adapted from Ref. 2 “Enhanced Host  
Controller Interface Specification for Universal Serial Bus Rev. 1.0”.  
The integrated high-performance Hi-Speed USB transceivers enable the SAF1760 to  
handle all Hi-Speed USB transfer speed modes: high-speed (480 Mbit/s), full-speed  
(12 Mbit/s) and low-speed (1.5 Mbit/s). The three downstream ports allow simultaneous  
connection of three devices at different speeds (high-speed, full-speed and low-speed).  
The generic processor interface allows the SAF1760 to be connected to various  
processors as a memory-mapped resource. The SAF1760 is a slave host: it does not  
require bus-mastering capabilities of the host system bus. The interface can be  
configured, ensuring compatibility with a variety of processors. Data transfer can be  
performed on 16 bits or 32 bits, using Programmed Input/Output (PIO) or Direct Memory  
Access (DMA) with major control signals configurable as active LOW or active HIGH.  
Integration of the TT allows connection to full-speed and low-speed devices, without the  
need of integrating Open Host Controller Interface (OHCI) or Universal Host Controller  
Interface (UHCI). Instead of dealing with two sets of software drivers, EHCI and OHCI or  
UHCI, you need to deal with only one set, EHCI, that dramatically reduces software  
complexity and IC cost.  
2. Features and benefits  
Automotive qualified in accordance with AEC-Q100  
The host controller portion of the SAF1760 complies with Ref. 1 “Universal Serial Bus  
Specification Rev. 2.0”  
The EHCI portion of the SAF1760 is adapted from Ref. 2 “Enhanced Host Controller  
Interface Specification for Universal Serial Bus Rev. 1.0”  
Contains three integrated Hi-Speed USB transceivers that support high-speed,  
full-speed and low-speed modes  
Integrates a TT for original USB (full-speed and low-speed) device support  
Up to 64 kB internal memory (8 k × 64 bit) accessible through a generic processor  
interface; operation in multitasking environments is made possible by the  
implementation of virtual segmentation mechanism with bank switching on task
